| Summary: | 碩士 === 國立台北護理學院 === 護理研究所 === 92 === The purpose of the study was to investigate the changes in perceived stress, acute stress disorder, anxiety, depression and posttraumatic stress disorder from hospitalization to one-month following discharged in patients with severe acute respiratory syndrome (SARS). A purposive sample of 90 hospitalized SARS patients were recruited from two major hospitals located in northern Taiwan. The measures included the Stress Visual Analog Scale (VAS)；the Anxiety and Depression Scale（HADS）；and the Posttraumatic Stress Disorder-Reaction Index（PTSD-RI）. Data were collected at 3-5 days during hospitalization and one-month following discharged from hospital. Data were analyzed by mean, standard deviation, percentile, dependent sample t-test, Pearson’s correlations and hierarchical multiple regressions.
The results showed that the prevalence rate for PTSD was 67.7% at the 3 to 5 days during hospitalization and 28.9% at one-month following discharge from the hospital. Patients reported significantly lower scores of PTSD in one- month following discharged from hospital than the 3-5 days during hospitalization（p<.001）.The prevalence rates of anxiety at the 3-5 days during hospitalization was 50% and one- month following discharged from hospital was down to 10%. There was significantly lower Anxiety scores at one- month following discharged from hospital（p<.001）. The prevalence rate of depression at the 3-5 days during hospitalization was 53.3% and one-month following discharged from the hospital was 17.8%. There was significantly lower depression scores at one-month following discharged from hospital（p<.001）. Data demonstrated that PTSD was positively correlated with perceived stress levels（r=.24 , p＜.05）, ASD（r=.57, p＜.001）, anxiety（r=.47, p＜.001）, and depression（r=.38, p＜.001）.
The hierarchical multiple regressions showed that perceived dyspnea, family isolation, perceived stress, reexperiencing, avoidance and hyperarousal explained 41.9% of the variance in PTSD at one-month following discharged from the hospital. Dyspnea and family isolation explained 13.7%（p<.001）,. perceived stress levels explained 4.4%（p<.05）,. Reexperiencing, avoidance and hyperarousal explained 23.9% （p<.001）of the variance in PTSD.
Results of this research provide vital important information for health professionals to caring patients with severe acute respiratory syndrome.
